Join Penn and Stella on their latest adventure...

There's a legend in the Sea Islands that before a hurricane hits the Gray Lady can be seen walking down the beach warning of doom. Penn doesn't believe in such silly stories, but she does believe weather forecasters. A powerful hurricane is heading their way. Joe Davies, a local treasure hunter with an unquenchable sweet tooth, claims to have seen the Gray Lady walking toward him just that morning and is terrified for his life.

After the storm passes everyone returns to survey the damage. As Penn walks her little dog Stella on the beach, she finds Joe Davies' body washed up onshore. Did the Gray Lady claim another victim? Many on the island believe that is exactly what happened.

Penn is sure there's another explanation. She follows the clues and hints of lost gold to discover that the truth behind the treasure hunter's death is as much of a maze as the boating channels winding their way through the local marshes.
